A method backed by science

You're probably thinking: “Woooooow, cool app… but does it actually work?”

It works. Without reviewing, your brain throws away up to 70% of what you studied within days.

Card.ai makes you review at the exact moment you were about to forget — and every review makes the memory stronger.

Can't deny it: Anki also uses spaced repetition and is one of the best apps out there. But, Card.Ai is easier. Use AI to help you study, create manually, study and review anywhere and anytime with the app and a simple interface.

Real students, different exams, same result: they stopped forgetting.

B
“Card.AI completely changed my way of studying Biology at UFRJ. I no longer waste time printing or transcribing cards: just create, save, and review them on my phone before class. The design is clean, creation is ultra-fast, and it helps me stay focused without facing a giant document. Thanks to the platform, my GPA rose to 9.4 this semester!”

“I didn't know about online flashcard platforms. I've tried doing it manually, but it takes a lot of time. A friend told me about Anki, I found it amazing, but it's all manual. It takes time. The one from you guys with automatic creation with AI and can put the PDF is amazing. I'm loving it. I've been studying for almost 2 years and neglected reviews, I didn't feel like I was advancing by doing questions.”
